LOOSE-LEAF DEVICE.

Specification of Letters Patent.

Patented Feb. 12, 1918.

Application filed March 20, 1914. Serial No. 825,948.

To all whom it may concern:

Be it known that I, KENNETH L. EDDY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Loose-Leaf Devices, of which the following is a specifica- My invention relates to that class of devices which are designed to raise a card or a predetermined groupof cards in a card index.above their normal position.

Devices of this character, with which I am familiar, are capable only of raising very small cards, and are not suitable to raise a number of large envelops, file Wrappers or binders such as are used in filing devlces.

My invention has for its object to provide a device which can be applied to a filing cabinet and which will be capable of raising any number of large size file wrappers without regard to their weight.

My means of accomplishingthe foregoing may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which:

Figure 1, is a fragmentary sectional view of a filing device equipped with my improvement.

Fig. 2, is a front or end view of the same.

Figs. 3, and 4, are detail views of the operating mechanism.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, 1, is the casing or containing case which is provided with a front M1112, and rear wall 3; the front wall is provided with a slot 4, in which is mounted a shaft 5. which isprovided with a hand wheel 6. The front wall 2, is provided with the letters of the alphabet in a horizontal row as at 7, and a pointer 8, carried by the front carriage, is arranged to register with the desired numeral.

The shaft 5, extends inwardly and is journaled in the walls 9 and 1Q, of a carriage. A gear 12, is carried on the shaft intermediate the walls 9 and 10 of the carriage, and is adapted to engage the teeth of an intermediate gear 13, mounted upon a shaft 14, also journaled in the walls 9 and 10 of the carriage.

The teeth of the intermediate gear 13, are in engagement with the teeth of a pinion 15, fixedly mounted upon a shaft 16, which has secured thereto suitably spaced, two worms 17 and 18, which are designed to engage two segmental worm gears 19 and 20. These segmental gears are pivotally mounted between guides 27 and 28, which are secured to the tie rods 21 and 22.

The carriage in which the train of gears is mounted, is connected by the tie rods, 21 and 22, to a similar carriage located in the rear of the casing 1, and upon these tie rods, which extend beyond the walls of the carriages, are mounted pinions 23 and 24, which are adapted to engage racks 25, which are suitably secured to the bottom wall of the casing 1. The worm gears 19 and 20,

are segmented in order that their forward ends which are slightly curved may engage a rising bar 26. This bar slides between guides 27 and 28, these guides being provided with slots 29 and 30, in which are mounted lugs 31 and 32, which project outwardly from the sides of the rising bar 26. These guides insure the vertical movement of the rising bar.

The operation ofmy device is as follows:

The file wrappers are provided with downwardly depending clips preferably formed of metal, the lower ends of which are adapted to engage or be engaged by the rising bar 26 in its upward movement. The lower edge of the file wrappers or envelope are provided with suitable numerals or letters corresponding to the numerals or letters 7, on'the front of the box or casing 1, and the clips are secured to the lower edge in the spaces designated by these letters or numerals. The operator then grasps the hand wheel and moves it laterally until the pointer registers with the desired letter, when by rotating the hand wheel, the train of gears will be set in motion, and the worms will revolve and the worm gear segments will be caused to move upwardly, their rounded ends 34, engaging the rising bar 26, and will cause the latter to be elevated and this in turn, engaging the lower ends of the metal clips or pins, will elevate the file wrappers or envelops.

It will be apparent to persons skilled in the art, that a very slight effort will be suttL cient to raise the heavlest weights with this construction.

Having described m invention what I regard as new, and desire to obtain by Letters Patent is:

1. In a device for raisin one or more binders, havin metal clips epending from their lower e ges, the combination with a casing adapted to hold binders, of a rising bar, adapted to engage said clips, a worm and gear mechanism adapted to elevate the rising bar, a shaft which carries the worm, and a pinion on said shaft, a train of gears on-eof which engages said pinion, means to rotate the said gears, said raising mechanism and gears being movable laterally across the casing.

2. A device for raising one or more binders, having a plurality of characters on their lower edge, and metal clips depending from the lower edge thereof and being adjustable longitudinally thereon, comprising the combination with a casing, of a rising bar adapted to engage a predetermined number of said clips, a worm and gear mechanism adapted to elevate the rising bar, a shaft which carries the worm, a pinion on said shaft, a train of gears one of which engages said pinion, sald rising mechanism and'gears be ing movabletransversely across the casing,

naeaaee a plurality of characters on the front of the casing in positions corresponding to the characters on the binders, and an indicator secured to said rotating mechanism for the purpose set forth substantially as described.

3. A device for raising one or more binders, having a plurality of characters on their lower edge and metal clips depending from the lower edge thereof, comprising the combination with a casing adapted to hold the binders, of a rising bar adapted to engage a predetermined number of said clips, a worm and gear mechanism adapted to elevate the rising bar, a shaft which carries the worm, a pinion on said shaft, a train of gears, one of which engages said pinion, means to rotate the said gears, a carriage in which said train of gears is mounted, a carriage in the rear of said casing, tie rods which secure and hold said carriages in 'alinement, pinions carried by said rods, racks mounted on the bottom of the casing which engage the teeth of the pinions, a

plurality of characters on the front of the casing in positions corresponding to the characters on the binders, and an indicator secured to said first-mentioned carriage for the purpose set forth substantially as described.

In witness whereof I have signed the foregoing specification.
